Jaguar first pulled the sheets on its XF mid-size luxury sedan in 2007 at the Frankfurt Motor Show. Since then, the lithe four-door has collected a good deal of critical praise, not to mention more than its fair share of sales. The second generation was introduced just last year, bringing significant updates like a lightweight aluminum body and higher levels of performance. Customers loved it, and the XF contributed nearly 29 percent of Jaguar’s total global fleet volume for the first 6 months of the year. Now, Jag is looking to keep the ball rolling, and it added new diesel power paired with AWD traction in order to do so.
